No special input devices needed, as all of the buttons on the keyboard will create a random swatch of color along with one of several sound effects. Pretty basic. Just beware of installing on a laptop, my kid began to pick the keys off!

How is this newsworthy?

And that book should be "Why Marriages Succeed or Fail" by John Gottman. Its not a geek book, but it was written by a psychologist who has studied marriage and married couples for over 20 years. My wife and I read it and our marriage is stronger for it. I wholly recommend it.

I'm finding myself in the same boat, but for a different reason. All it will take is one pointy-haired exec to look at this model and think, "We're not getting paid enough!" Then that label pulls out of the 'scheme,' bringing countless songs into legal-limbo. It sounds like a great idea, conceptually, but a lot of logistical wrinkles need to be worked out before I consider it seriously. Great pipe dream, though.
